IMPROVEMENT IN MACHINES FOR PACKING FLOUR.

Spccilieation fbrmng part of Letters Patent No. 106,912, dated August 30, 1870.

To all lwhom it 'may concern:

Be it known that I, BENJAMIN F. BAsHon, of Carters Depot, in the county of Carter and State of Tennessee, have invented a new and Improved Machine for Packing' Flour; and I do hereby declare the following to be a full and exact description thereof, reference being had to the accompanying drawing, making part of this specification, and to the letters and figures marked thereon.

My invention relates to a machine for packing our in sacks or bags; and consists in such an arrangement of devices or parts that the flour is conveyed through a tube to a 1101- low endless cylinder, which is lowered into the sack to be filled, and the flour rolled therefrom and packed in the sack by means of coneshaped rollers placed in the lower end of the cylinder and radiating horizontally from its center, which rollers are operated by means of an upright shaft suitably geared. The device is fixed in a suitable frame, and is provided with a sliding chain for holding the sacks and other necessary arrangements.

In the accompanying drawing, Figure l represents a sectional end elevation ofthe machine. Fig. 2 represents an inverted view of thepacking-cylinder, showing the position of the packing-rollers therein. Fig. 3 represents a side elevation of the machine, partly in section; and FigA. is af top view or plan of the machine.

Similar letters of reference indicate corresponding parts.

A A are the sides of the frame. I3 is the packing-cylinder, and b l) its upper and lower grates. C C are the packing-rollers, revolving on pinions rigidly secured in the lower end of the shaft D. d. is a gear-wheel, which revolves the shaft D. vThe shaft D moves up and down through this gear-wheel, and is provided on one side with the vertical key d', which occupies a corresponding ward in the wheel d, and it is by means of this key and ward that the shaft D is revolved by the wheel d. a a are cross-beams, which act as braces for the frame, a stop for the rising of the packing-cylinder,and a seat for the wheel cl. E is a stirrup, pivoted to the top of the shaft D. The object of this stirrup is to prevent the chain f from twisting with the revolving of the shaft D. is secured in the stirrup E and the other made to slide in a slot in one side of the frame. F is aweigllt, which assists the rising of the pack ing-cylinder B as the flour is packed in the sack. g is a spur in the side ofthe shaft/l). The object of this spur is to stop the revolution of the shaftD by disconnecting the gearing, which it accomplishes as follows: As the bag fills with 4flour the shaft D and cylinder B rise up out of the salne until the top of the cylinder B reaches the under side of the lower beam a, when the spur g connects with the spur g in the sliding bolt G and moves it from left to right, thereby throwing the foot of the supporting-pand h of the beam H out of its seat in the side of the frame of the machine. H is a rocking beam, forming the bearin gof the gear-wheel I, which connects with and operates the shaft-wheel d. This beam is run through an opening in the right side of the frame of the machine and pivoted therein. Its inner end rests on aseat in the left side of the frame, and its outer side is provided with the weight h and the supporting-pawl l1'. The foot of the pawl h rests in a seat in the side of the frame and holds the beam in position.

IVhen the sliding bolt Gis moved to the right, as before described, and has thrown the foot of the supporting-pawl h out of its seat, the weight h carries down the outer end ot' the rocking beam H, and thereby disconnects the gear-wheels d and I, and assumes the position shown by the dotted lines.

O is the balance-wheel of the machine, and Ol is its pulley or driving-wheel. J is a tube through which the iiour is conveyed to the packing-cylinder B. a is the top of the frame, and f j" are friction-wheels placed therein to accommodate the chain j'. k is a shelf through which the packii'lg-cylinder moves.

The cylinder Bis provided on its sides with the keys b2 b2, which occupy corresponding wards in the shelf k, and prevent the cylinder from taking any other movement than a vertical one.

L is the sack-chair. This chair is provided with the ...open sack-seats m m, in which the sacks to be lled are hun g.

The operation of my machine is as follows:

c is an arm, one end of which The sacks to be filled are hung, in the seats l on m of the chair L, and the chair slid in under the shelf k, so that one ofthe seats will come under the end ofthe packingcylinder B, which is lowered into the same. rIlhe flour is then run into the cylinder through the tube J- and the machine put in motion. As the ilonr falls it is packed in the sack by means ot' the rollers C C revolving over it and pressing it down in a continuous layer. As the iiour is packed the rollers C C rise, carrying` with them their shaft and the cylinder B, until the spur f/ comes in contact with the spur g and stops the machine, as before described. One ofthe sacks being` now packed the chair L is moved, so as to bring1 the empty sack under the cylinder7 when the operation is commenced anew, the full sack being' removed and replaced by an empty one.

Instead of the rocking beam II and the other devices herein described for disconnecting` the gear-wheels d and I, a sliding` pulley may be used, and the machine may also be so geared as to automatically shut oit' the supply of onr from the cylinder while the chair is changing' position.

Having thus fully described the nature and operation of my invention, what I claim" as new, and desire to secure by Letters Patent, 1s-

l. 'Ihe packing-cylinder B, with its grates b b, in combination with the upright shaft I) and its packing-rollers C C, arranged and operating` as herein shown, and for the purpose described.

2. The rocking beam H, geamvheel I, pawl h., and weight h', in combination with the sliding bolt G, arranged and operating in the manner and for the purpose herein set forth and described.

3. The chair L, provided with the sack-seats m m, constructed, arranged, and operating in connection with the packing-cylinder I3, in the manner and for purpose herein set forth and described.

ln testimony that I cla-im the foregoing iiourpacking' machine I have hereunto set my hand this 26th day of May, 1870.
